Computerized Neuropsychological Assessment in Aging: Testing Efficacy and Clinical Ecology of Different Interfaces

Table 3

Mean RTs (along with SD) for each experimental condition used to calculate effects of ANT are shown in the table for both touch (upper panel) and mouse (lower panel) versions of the task. Congruent trials are subtracted from incongruent trials in order to calculate conflict effect, double cue trials are subtracted from no cue trials in order to calculate the alerting effect, and spatial cue trials are subtracted from central cue trials in order to calculate the orienting effect.
